Sparging (chemistry) (Redirected from Sparger) In chemistry, sparging, also known as gas flushing in metallurgy, is a technique which involves bubbling a chemically inert gas, such as nitrogen, argon, or helium, through a liquid. This can be used to remove dissolved gases (e.g. oxygen) from the liquid.
Sparging, also called lautering is a step at the end of the mashing process where hot water is run through the grain bed to extract a sweet liquid called wort. The wort is later boiled and fermented to produce beer. After the mashing process is complete, the grains, water and sugar are still in suspension in the mash container, called the mash tun.
